            Bug ID: 405491
           Summary: KMail (in Kontact) crashing upon start or shortly
                    after
           Product: kontact
           Version: unspecified
          Platform: Debian stable
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-b...@kde.org
          Reporter: hilb...@unix-ag.org
  Target Milestone: ---

Application: kontact (5.9.3)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-2-amd64 x86_64
Distribution: Debian GNU/Linux buster/sid

-- Information about the crash:
Open KMail (in Kontact), it crashes. If it does not, it will do so shortly
after. Open a few E-Mails and there you go.

I suspect that the crash might be due to graphics handling in the nouveau
driver. Experienced the same issue
on the nvidia legacy 390 binary driver.

Sometimes just before the crash I can see the message pane flashing in red
color.

This is not the latest KMail but the one packaged with Debian/Buster. I'd like
to file a bug with Debian referencing
this one on kde.org. They might need to backport an existing fix.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
